SPECIFICATION forming part of Letters Patent No. 738,770, datedSeptember 15, 1903.

` Application filed February 11,1903. Serial No. 142,920. (No model.)

,To all whom t may concern,.-

Be it known that I, MATTHEW BURTON, a

. citizen of the United States, residing at Batavia, in the county ofKane and State of Illinois, haveinvented certain new and usefulImprovements in Mechanical Movements, of which the following is aspecication. 4

The object of this invention is to provide a simple and inexpensivedevice forrotating a shaft, preferably anagitator-shaftof awashing-machine or churn, alternately in opposite directions by acontinuous rotary movement of a driving-shaft; and it consistsin certain`peculiarities of the construction, novel arrangement, and operationofthe various parts thereof, as will be hereinafter more fully set forthand specifically claimed.

The improvement is susceptible of various changes in the form,proportion, and minor i my invention, showing it mounted ou a por- Ydetails of construction without departing from the principle orsacrificing any of the advantages thereof, and a full disclosure of theinvention and adaptation of the same is shown in the accompanyingdrawings, in whiche- Figure 1 is a view in side elevation and partly insection of a movement embodying tionof the top of a washing-machine orchurn;

and Fig. 2 is a plan view taken on line 2 2` of Fig. 1 looking in thedirection indicated by` Washing-machine, but it may represent a portionof a churn or other vessel in which it is` desired to agitate or stirthe contents thereof. Mounted on'the top or lid 6 of the vessel is `thesupportingframe 7 of my movement,

which frame may be made of any suitable size, form, and material, butpreferably of the shape shown in the drawings. Vertically journaled inupper and lower extensions@ and 9, respectively, of the supporting-frame`is a rotary reciprocal or agitator shaft 10, which passes through thecoveror lid 6 of the tub `or other vessel and has suitably mounted onits lower portion an agitator or dasher 11 of any desired construction.The shaft is ,provided with a worm 12 to engage a wormgroove 13 on theinner surface of the sleeve 14, which is movably mounted on said shaft.This sleeve is furnished with a vertical rackbar 15 and has on each sideof said rack-bar a guide-flange 16, which serves to hold the rack-bar inengagement with the beveled pinion 17, which is mounted on the innerportion of the driving-shaftlS, which shaft is journaled on thesupporting-frame 7 and carries on its outer portion a crankwheel19,usedfor turning the same.

By rotating the driving-shaft 18 continuously in one direction it isapparent that the pinion 17 thereon will engage the teeth of therack-bar first on one of its surfaces until it reaches the end thereof,when the pinion will pass over the end of the rack and engage the otherside of the teeth thereof, thus causing the sleeve 14 to movelongitudinally Aon the worm portion of the shaft 10, sopas to impartthereto a rotary reciprocal or alternating rotary movement, in whichoperation the flanges 16, which are located far enough from the rack-barto receive the inner end of the driving-shaft, will hold the rack-bar inpositive engagement with the pinion.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isi 1.V Ina mechanical movement,rthe combination with a rotary reciprocal shaft, of a sleeve movablymountedthereon and in wormthread engagement therewith, a rack locatedlongitudinally on said sleeve, a continuouslyrevoluble shaft, and apinion thereonto en gage the rack, substantially as described.

2. In a mechanical movement, the combination with a rotary reciprocalshaft, of a sleeve movablymounted thereon andin worinthread engagementtherewith, a rack located longitudinally on said sleeve, a guide-angelocated on the sleeve near each side of the rack, acontinuously-revolubl'e shaft having itsl inner end projected so as toextend between said flanges and rack, and a pinion on said shaft toengage the rack, substantially as described.

3. In a mechanical movement, the combinationwith a rotary reciprocalshaft provided with aworm, of a sleeve movablymounted on said shaft andhavmg a groove to receive the Worm thereof, a rack located longitudi-ICO 2 l @Semo nally on said sleeve, a continoiisly-ievoluble sleeveiiear ea'eh side ofthe raelQ a continii- 16 shaft, and apinionthereon'to engage the rack, ous revoluble shaft having its inner endprosubstantially as described. jected so as to extend between saidflanges 4.
